Using Instrumental Variables to Evaluate LLM Routing Decisions in Python
The excerpt explains that in multi-model gateways, simple regression can give misleading results because routing choices are tied to query difficulty. A premium-vs-cheaper model comparison can mix the model’s effect with the fact that harder queries are routed differently. It introduces instrumental variable analysis as a way to separate these effects using a third factor that changes routing without being related to query quality.

How to Build AI Apps That Switch Models Automatically
The article explains why using one AI model for every request can be risky: outages can freeze an app, expensive models can raise costs, and smaller models may struggle with harder tasks. It describes a Python-based multi-model orchestrator that routes prompts by complexity and intent, then falls back to another model automatically. The guide also covers setup, package installation, and combining the pieces into one pipeline.
